In brief: Causes of COPD

The biggest single cause of COPD is smoking.


If you stop smoking, your chances of developing COPD begin to fall. If you already have COPD, stopping smoking can lead to an improvement in your symptoms and mean it progresses more slowly.

You are also more likely to get COPD:


• if your job exposes you to certain dusts or fumes
• from environmental factors, such as air pollution
• from inherited problems - an inherited shortage of a protein called alpha antitrypsin that helps protect your lungs from the effects of smoking may increase your risk, but fewer than one in 100 people with COPD have this


Allergies and asthma have also been suggested to increase your chances of getting COPD, but the evidence is not conclusive.
